David or Sergey, I guess back to my original question....except this should be a bit more clear.
I'm using apache's httpclient in order to process POST and GET requests to my REST service methods. These POST and GET requests are being executed from a JSF managed bean in order to retrieve an object and then perform operations on that object before displaying it in a xhtml page. While using xml I'm able to return the HttpResponse from the service method and use the HttpResponse.getBodyAsString() along with JAXB in order to convert the xml string to an object. For JSON, what would be the best way to return the JSON string and then convert that to an object so that I can return that to the consumer of the service method (JSF managed bean) in order for it to perform operations on it?
